Abdominal swelling, or distention, is a common condition, which usually results from over-eating, rather than from a serious illness. Simple weight gain , premenstrual syndrome (PMS) , pregnancy, or the unconscious swallowing of air can lead to this problem.

Abdominal distention is often due to gas in the intestines. This may result from eating fibrous foods such as fruits and vegetables. Beans are common sources of intestinal gas. Dairy foods can lead to abdominal swelling if you are lactose intolerant.

Abdominal swelling may also occasionally result from the accumulation of fluid in the abdomen, which can be a sign of serious medical problems. There are usually other symptoms in this case.

A swollen abdomen that results from eating a heavy meal will go away when the food is digested. Eating in moderation will help prevent swelling.

For a swollen abdomen caused by swallowing air, awareness often leads to self-control. Eat slowly, avoid carbonated beverages, avoid chewing gum or sucking on candies, avoid drinking through a straw, or sipping the surface of a hot beverage.
